A process is described for the diffusion or metallizing of one electrically conductive metallic material into and on to the matrix of a second electrically conductive metallic material. The process will occur when the second material is in a solid state condition and placed in closely spaced but not touching contact with the first conductive material, and both are subjected to an applied D.C. potential across the materials while the first metallic material is subjected to an ultrasound signal. The first material and the second material thus form an electrode pair. The material of the second metallic element is then deposited on the first and the first metallic material is effectively metallized by the second material. The material to be coated is moved, e.g., rotated, during the process while maintaining a small gap with respect to the other electrode. Also disclosed is a relatively simple apparatus for carrying out the method of this invention. Such apparatus basically includes an ultrasonic generator, a workpiece holder, mounting attachments for mounting the material to be coated on the ultrasonic horn, a D.C. and A.C voltage supply and a device to effect movement and rotation of the workpiece relative to the horn.
